Architecture

The architecture of Laralord is designed to provide a robust, scalable, and secure foundation for multi-tenant SaaS applications. This section outlines the core components of the architecture, including the ingress gateway, secrets management, Kubernetes orchestration, and integration with third-party services. Understanding this architecture is key to leveraging Laralord’s full potential for your SaaS deployments.

High-Level Overview

Laralord’s architecture is built on a microservices model orchestrated by Kubernetes, with a focus on security, scalability, and ease of management. The key components include:

• Ingress (APISIX Gateway): Manages incoming traffic and routes requests to the appropriate tenant services.
• Secrets Storage (Vault HashiCorp): Securely stores and manages credentials, secrets, and access keys for tenants.
• Kubernetes Services and Deployments: Orchestrates the deployment of tenant applications using the laralord-project/server image.
• Third-Party Services: Integrates with databases (SQL, Redis, OpenSearch) managed via the Laralord API for tenant-specific configurations.

This architecture ensures that each tenant’s data and resources are isolated while sharing the underlying infrastructure efficiently.

Ingress (APISIX Gateway)

The ingress layer is powered by Apache APISIX, a high-performance API gateway that handles all incoming requests to the Laralord platform. APISIX is responsible for:

• Routing requests to the correct tenant’s Kubernetes service based on domain or path.
• Enforcing security policies, such as rate limiting, IP whitelisting, and authentication.
• Managing TLS certificates for secure HTTPS communication.

By using APISIX, Laralord ensures that traffic is efficiently distributed and secured before reaching the tenant’s application.

Secrets Storage (Vault HashiCorp)

HashiCorp Vault is the backbone of secrets management in Laralord. It securely stores and manages sensitive information, such as:

• Database credentials for tenant-specific databases.
• API keys and access tokens.
• Encryption keys for data at rest.

Vault’s integration ensures that secrets are encrypted, access-controlled, and auditable, providing a high level of security for each tenant’s data.

Kubernetes Services and Deployments

Laralord leverages Kubernetes to orchestrate the deployment and scaling of tenant applications. Each tenant’s application is deployed as a Kubernetes Deployment using the laralord-project/server image, which provides the runtime environment for tenant-specific workloads.

• Deployments: Manage the lifecycle of tenant applications, ensuring they are always running and can scale based on demand.
• Services: Expose the deployments internally within the cluster, allowing APISIX to route traffic to the correct tenant’s service.

Kubernetes’ autoscaling capabilities ensure that tenant applications can handle varying loads efficiently, while maintaining isolation between tenants.

Third-Party Services

Laralord integrates with various third-party services to provide a complete SaaS infrastructure, managed via the Laralord API. These services include:

• SQL Databases (PostgreSQL, MySQL): Each tenant has its own database instance for data isolation.
• Redis: Used for caching and session management, with tenant-specific configurations.
• OpenSearch: Provides powerful search and analytics capabilities for tenant data.

The Laralord API is an external API that manages tenant dependencies, such as creating databases, generating Redis credentials, and configuring OpenSearch instances. This ensures seamless onboarding and management of tenant-specific resources.

Conclusion

Laralord’s architecture simplifies the complexities of multi-tenant SaaS deployments. By leveraging APISIX for ingress management, Vault for secure secrets storage, Kubernetes for orchestration, and the Laralord API for managing third-party services, it provides a robust, scalable, and secure platform for your SaaS applications. This design ensures tenant isolation, security, and ease of management, allowing you to focus on delivering value to your customers.
